Design of Tailing Lug for replacement of tube bundle for Vertical Heat Exchanger

Design of Tailing Lug for replacement of tube bundle for Vertical Heat Exchanger

(OP)
Good day to all,

Do you have any idea on how tube bundle lifted from horizontal to vertical position?

Also do you have any experience on designing a lifting lug, flange and tailing lug attached to tube bundle?

Thanks.

Yes, & yes

Hi SnTman,

Thanks.

Can you share your design experience regarding this, and do you have any calculation for this?

Thank you.

RE: Design of Tailing Lug for replacement of tube bundle for Vertical Heat Exchanger

WorleyP, you need to lift the load from two points, usually using two cranes. When lifted high enough the load is then re-oriented by lowering the bottom end. If possible, the upper end should be lifted above and near the to the CG to minimize the load on the tailing (lower) end, using trunnions if possible. This is more complicated for a bundle only. The upper end will need to be lifted at the upper tubesheet, by lugs or eyebolts attached to the same. The lower end may be supported by some arrangement attached to the lower tubesheeet, or by a clamshell arrangement either of which is removed after turning the bundle.

The lugs, trunnions and associated hardware is designed per good engineering practice.

Standard pressure vessel handbooks such as Moss show these kinds of calculations.

Regards,

Mike
